Overview
This HTS classification, 7304.29.10.40, specifically covers seamless casing made from iron or non-alloy steel. These pipes are designed for use in the demanding environments of oil and gas drilling operations. A defining characteristic of this subcategory is their substantial wall thickness, which must be 12.7 mm or more. This robust construction is critical for withstanding the high pressures and stresses encountered during drilling.
The distinction between this classification and its sibling, 7304.29.10.30, hinges entirely on wall thickness. While both are seamless iron or non-alloy steel casing used in oil and gas drilling with an outside diameter between 215.9 mm and 285.8 mm, the 7304.29.10.30 category encompasses those with a wall thickness *less* than 12.7 mm. Therefore, a product's wall thickness is the sole determining factor in choosing between these two closely related classifications.
As a leaf node, this category represents the most granular level of detail within its hierarchical path. It does not have further subcategories, meaning any seamless iron or non-alloy steel casing meeting all the preceding criteria (used for oil/gas drilling, threaded or coupled, outside diameter 215.9 mm to 285.8 mm) and having a wall thickness of 12.7 mm or more would be classified here. Examples would include heavy-duty casing designed for deep well exploration or production where extreme structural integrity is paramount.
